WATER-HEATER.

'SPECIFICATION forming part of VLetters Patent No. 714,641, dated November 25, 1902.

Application led December 18, 1901. Serial No. 86,363. (No model.)

To @ZZ whom, it may concern.-

Be it known that I, JOSEPH M. FOX, a citizen ofthe United States, and a resident of Peekskill, in the county of Westchester and State of New York, have invented a certain `new and useful VVater-I-Ieater, of which the following is a specification.

`closing the said parts.

This invention relates to devices for quickly heating water, and more particularly to forms of heaters made of cast metals.

It has for its object a convenient form of casting heating-surfaces that shall present areas to` the action of the heat that are unusually large in proportion to the spaces occupied by the water.

The objects are attained by the means set forth in this specification and the accom panying drawings.

The drawings consist of four iigures, in which like parts are designated by similar numbers and letters.

Figure l represents the heater in elevation and in partial section and crosssection. Fig. 2 is a plan of a heater-section viewed from the top of the heater and shown partially in section. Fig. 3 is a plan of a jacketing-ring. Fig. 4t is a view of one part of the jacketingv support.

Fig. l shows this heater to be composed of three water-sections d a a, united to each other at their centers and connected with water-pipes 7 8, a gas-burner, and a casing in- The three sections are united by throats 3 and are represented as one integral casting, the form in which they are preferably made. The shape selected for representation is the circular, and

` the tops and bottoms of the sections slope apart toward their centers, their depth being greatest at their centers. The advantages of this shape are found in the ample air-space afforded between the sections, which improves the draft through the heater, and the iowing heat currents make as ready contact with the top of one section as with the bottom of the one next above it, andthe slope given to the waterways prevents deposits from the water.4 Each section is provided with an inner chamber e, through which the heat circulates as readily as around the outside of the section, the lues 'n affording com- -by means of the hub 9.

`12 being shown. upon the plate w, as indicated by the broken munication with the chamber. The walls of the lues n support the casing forming the chamber, and the fines are the only obstruction to the circulation of water all around the casing. The casing is preferably made to conform in shape to the outer casing, so as to give a uniformity of water-spacef. Water entering the sections by the pipe '7 will meet the walls of the inner chamber e and to reach the passage 72, to the next section must liow against the entire surface of the outer casing and also of the inner casing, part of it at the same time having contact with the walls of the liues n, so that in the space usually occupied by one heater-section nearly double the heating-surface is obtained. Fig. 2 further illustrates the construction ofthe section, the top plate 1 being cut away, revealing the inner top and bottom surfaces of the walls forming the chamber c. Water` entering the inlet at c Hows between the plates l and 2 to and between ,plates 3 and 4 to reach the outlet h. The lues n are limited to two in a section when several sections are cast together for obvious conveniences in molding. Itis, however, plain that these sections may be made singly and be connected with nipples in the manner commonly employed for connecting heater-sections. When so made-that is, singly-the number of fines may be increased, since in that case they would not require to be molded edgewise. When the sections are mounted upon the pipe 8, a supporting-plate w is secured to the pipe A gas-burner l0, annular in form and having a supply-tube 11, is secured to the plate w, one fastening-foot A base m is adapted to fit lines 13, Fig. l. This base is provided with a rising langep. Encircling said iiange is a i ring r. (Shown in plan in Fig. 3.) The upper end Z of said ring receives a sheet metal jacket Av, which finds lodgment upon a projection 0 on the inner side of the ring. To the lower portion s of the ring another jacket u is secured. This ring, with the jackets u c thus attached to it, is easily removable from the base, so that when the jacketing is completed by the attachment of the top t the entire jacketing may be lifted bodily from the IOO bastion.

base. Thus easy' access is given to the heatersections for cleaning them. The top t is provided with an outlet 6 for the gases of com- To sustain some of the weight of the jacketing and prevent its all coming upon the plate w, a foot-piece 7, Figs. 1 and 4, having a rim 5, rests upon the top heater-section. The cast top irests at its center upon the rim 5. This supporting-foot encircles the pipe 7.

' Having described my invention, what I claim, and desire to secure by Letters Patent of the United States, is-

l. The combination in a water-heater composed of two or more sections one above the other integrally united to each other at their centers, of sections made with their tops and bottoms sloping from' their centers to their outer edges giving to the sections their greatest depth at their centers and atfording airspaces between the sections of greatest depth at their edges, a water-pipe entering the lower section, a supporting-plate secured to said pipe, a base and a gas-burner attached to said plate, a jacketing comprising a top, sheetmetal sides and a ring to which said sheetmetal sides are secured, said ring and attachments removably adjusted to said base, and a jacket-supporting foot-rest on the top section, substantially as herein set forth.

2. In a Water-heater a section comprising an outer casing and an inner casing forming a water-space between them and an air-space within the inner casing, the inner casing entirely surrounded by water except at its flue connections, the two casings connected together with and the inner casing integrally supported by iiues that afford gas-openings to the inner chamber.

3. A water-heater section comprising an outer casing and an inner casing forming a Water-space between them and an air-chamber within the inner casing, the inner casing conforming to the shape of the outer casing and entirely surrounded by water except at `its flue connections, the two casings united with and the inner casing integrally supported by the walls of iiues that afford gasopenings to the inner chamber.

4. A heater-section consisting of an outer casing and an inner casing forming a waterspace between them and an air-chamber within the inner casing, the inner casing entirely surrounded by Water except at its flue connections and conforming in shape to the outer casing, the tops and bottoms of the casings sloping from the centers of the sections to the outer edges giving upward sloping waterpassages throughout the section, the inner casing integrally connected with the outer casing by the'walls of the flues that support the inner casing and aord gas-openings to the inner chamber, substantially as set forth.
